某人的电子邮箱为Pyxdl@yinfu.com。对于Pyxdl和yinfu.com的正确理解为 3 ，在发送电子邮件时，常用关键词使用中， 4 是错误的。若电子邮件出现字符乱码现象，以下方法中 5 一定不能解决该问题。 11 在实验阶段进行，它所依据的模块功能描述和内部细节以及测试方案应在 12 阶段完成，目的是发现编程错误。 13 所依据的模块说明书和测试方案应在 14 阶段完成，它能发现设计错误。 通常，软件开发环境可由环境机制和工具集构成。按功能划分，环境机制又可分为 15 ；工具集也可分为贯穿整个开发过程的工具和解决软件生命周期中某一阶段问题的工具，分别属于上述两类工具的是 16 。软件开发环境的核心是 17 。软件开发环境具有集成性、开放性、 18 、数据格式一致性、风格统一的用户界面等特性，因而能大幅度提高软件生产率。 一般说来，信息化需求包含三个层次，即 19 、 20 和 21 。 根据制定机构和适用范围的不同，标准可分为若干个级别，如国际标准、国家标准、行业标准和企业标准等。
ISO属于 22 、IEC属于 23 、GB属于 24 、IEEE属于 25 。 外围电路中某电路，使用8K×4位的SRAM存储器芯片构成256K×32位的Cache存储器。 26 片，存储器地址码位数是 27 ，单个芯片的地址码位数是 28 。 EPROM是 29 ，计算机内存主要由 30 导体存储器构成。 网络操作系统(NoS)的基本组成是 51 ；下列对于NoS的说法中， 52 是不正确的；下列 53 不属于NetWare网络的基本硬件组成；Windows NT的执行体基本上是一个完整的操作系统，它由一组部件构成，这些部件是 54 ；在Windows NT的执行体的各组成部件中，对中断和异常做出响应，调度线程，提供一组基本对象和借口的部件是 55 。 UML-based tools are often used for J2EE/.NET application analysis and design, both because UML's object orientation is ideal for the J2EE/.NET implementation 66 and because of the expanding scope and complexity of today's enterprise endeavors. 67 the approaches diverge at the coding/implementation phase, a common set of analysis and design techniques applies to both J2EE and.NET.
The use of a virtual machine (VM) architecture is also common to J2EE and .NET. Application development tools 68 intermediate-level code instead of platform-specific binary code, which means the VM interprets that code in real time or performs Just-In-Time (JIT) compilation; the Microsoft VM always runs JIT-compiled code. This VM-based model results in 69 -independent applications and is conducive to the late-binding technique that's 70 to the OO approach. Due to a constantly 71 environment, a poor understanding of the user's needs and preferences, as well as a 72 of willingness to modify 73 organizational structures and decision models, the full economic potential of Web.
Information Systems (WIS) has not been realized by now. The data object types of the 74 meta model, the Extended World Wide Web Design Technique (EW3DT), provide hypertext designers 75 a conceptual, user-centric framework and graphical notation for the construction of both, reference and customized models, during the software development process of commercial WIS. A reference model as a normative concept represents an abstraction of a typical company, its functional units, or its (Web) Information Systems and is intended to streamline the design and implementation of complex applications at reduced costs. As precondition for pursuing a partial globalization strategy, EW3DT distinguishes between technical and content-specific responsibilities for designing, implementing, and maintaining WIS.
